The problem is real and significant*. Multimodal evals are also a relatively underexplored area, even though consequences are significant.
Usually the limitation with these kinds of ideas is that they're essentially solving an extremely large surface area that a big lab is incentivised to work on themselves end-to-end (it's hard to make a useful robot that also randomly injures people so someone's usually working on Don't Make Your Robot Kill People), whereas for B2B what you almost always want is to solve something specific that removes the need to hire 1-2 people. That said, the problem descriptions are well-done and show an attention to detail and ability to iterate with real examples, so this is promising.
Perfect score would be granted for a clearer path to monetisation, either solving something the big labs would find hard to solve themselves, or providing a service that makes sense to outsource/use third party for. But tech-wise, this is pretty sound.
I actually know someone working on Dangerous Capabilities Evals at OpenAI who I pitched multimodal safety evals to, if you'd like an introduction :)
